The vacuum level is determined by the pressure differential between the evacuated volume and the surrounding atmosphere. Several units of measure can be used. Most refer to the height of a column of mercury â usually inches of mercury (in.-Hg) or millimeters of mercury (mm-Hg).
For the metal cylinders and the wire the volume is given by 22 4 dLVrL Ï==Ï (2) where r is the cylinderâs radius, d is the diameter (2r), and L is the length of the cylinder. For the irregular body the volume will be determined by measuring the volume of the liquid that it displaces.
